Y5-51 Boiler Fan, Y4-73 Boiler Fan, Y4-68 Boiler Fan G / Y5-51 boiler boiler-Fan, suitable for power plant 2-670t / h steam boiler air supply system, also meet the requirements of high-pressure fluidized bed boiler head performance parameters, fans of the series can also be used for dust, mine ventilation and general ventilation systems. Blower for general air transport, cited as flue gas fan delivered or particles containing impurities. When the magazine containing a concentration of less than 200mg / cubic meter used more than four years. Containing impurities such as large also be used, but life will be shortened. Induced draft fan must not exceed the maximum operating temperature of 250 ℃. ☆ Type a fan, fan and induced draft fan made single inhalation, each №8 ~ 29.5 total of 20 machine numbers. 2, from the motor end of the face, called D-clockwise rotation of the impeller fan, to the "right" means; impeller rotates counterclockwise called L-blower to "left". 3, fans of the negative port position to cabinet outlet point of that. 4, the fan drive way D-type, all with flexible coupling drive. 5, the full product name, for example as follows: G5-51№18D right left 0 ° 90 ° Y5-51№18D where G, Y denote the boiler fan and Boiler Fan. ☆ structure of a fan, fans of the series with a high-strength wear-resistant impeller, bearing housing oil spill prevention and other advanced technical achievements transfer. 2, high strength wear-resistant impeller. After the impeller blades to the board, to reduce the impact of air, good stability, easy to overload the motor, greatly extending the life of the fan. This type of fan pressure coefficient, low peripheral speed, impatient sound small, so good practicality. 3, anti-spill bearing housing. Using lap slinger with the high-speed rotation of the bearing oil thrown from the bearing housing to the inner wall of the oil back into the tank, side covers packing can have a small amount of lateral pressure light oil block, bearing upper tank vent plug has reduced bearing box slightly positive pressure to ensure that no oil spills, dust-proof effect. 4. The fan is a cantilever structure, convenient arrangement, direct drive motor, transmission torque evenly, reducing vibration so that the fan is running reliably.
